这里比较明显,数据库报大量ORA-600 kcbz_check_objd_typ_1错误之后,然后smon进程终止,实例crash.

这里可以看出来有block中的obj和dataobj不匹配.

查询seg$.type=3
type=3为临时对象,由于异常原因导致smon在清理temp对象无法正常完成,从而使得smon终止,实例crash.

ORA-600 kcbz_check_objd_typ_1处理方法

1) Check tablespace bitmap


SQL> oradebug setmypid 
SQL> exec dbms_space_admin.tablespace_verify('&TBSP_NAME') 
SQL> oradebug tracefile_name 

or if the tablespace involved is an ASSM tablespace: 

SQL> oradebug setmypid 
SQL> exec dbms_space_admin.assm_tablespace_verify ('&TBSP_NAME',dbms_space_admin.TS_VERIFY_BITMAPS) 
SQL> oradebug tracefile_name

I am expecting to fail 

2) Corrupt these temp segments 

SQL> exec dbms_space_admin.segment_corrupt('&TBSP_NAME', &FILE#, &BLOCK#) 

3) Drop them 

SQL> exec dbms_space_admin.segment_drop_corrupt('&TBSP_NAME', &FILE#, &BLOCK#) 

4) Rebuild tablespace bitmap


exec DBMS_SPACE_ADMIN.TABLESPACE_REBUILD_BITMAPS('&TBSP_NAME')


5) Verify the tablespace again 

SQL> oradebug setmypid 
SQL> exec dbms_space_admin.tablespace_verify('&TBSP_NAME') 
SQL> oradebug tracefile_name 

or if the tablespace involved is an ASSM tablespace: 

SQL> oradebug setmypid 
SQL> exec dbms_space_admin.assm_tablespace_verify('&TBSP_NAME',dbms_space_admin.TS_VERIFY_BITMAPS) 
SQL> oradebug tracefile_name
